l. lin combination, a bolster, an arcuate spring means mounted thereon, a truckv trame having an arcuate portion opposite the spring to permit the spring to pass such portion of the trame, and means connecting the said spring means to the said truck trame.`

2. in combination, a bolster, an arcuate spring means mounted thereon, a truck trame, the said truck rame having an arcuate portion opposite the spring to permit the spring to pass such portion ot the trame, and ineans connecting said spring means to said truck traine, said connecting means being adapted to permit lateral and orward'movement oi:l said bolster and spring means relative to said traine as well as the vertical movement due to the compression and expansion oit the spring means,

3. in combination, a bolster, spring means mounted thereon, a truck trame having an arcuate portion opposite the spring` to permit the spring to pass such portion ot the trame, and means to suspendsaid spring means from the ends oi the arcuate portion of the trame, and wheels to support said trame. 4

fi. in combination, a bolster, spring means mounted thereon, a truck traine, having an arcuate portion opposite thespring to permit the spring to pass suoli portion oi the frame, and means to suspend said spring means from the ends o' the arcuate portion of the irame, and wheels to support said trame, said suspending meansjbetween said spring and said traine, being adapted to permit forward and lateral relative movement ot' said spring means and bolster relative to said trame. .Y

5. ln combination, ay transverse bolster, a truck trame having an arcuate portion, brackets extending` from the ends of said trame and attached to axles and wheels, spring means mounted on the ends oi' said bolster in the space between the ends ot' said larcuate portion of the truck trame, supporting blocks mounted on the ends ot said ar- `cuate port-ion, links depending therefrom having their free ends connected toV said .ing blocks mountedon the ends of said arcuate portion, links depending therefrom having their -tree ends connected to said spring means, said linksy being arranged to turn lat-r erally with said blocks and to rotate freely fore and att in said blocks, and means to support said blocks on the ends of the arcuate portion of the trame to permit said rotation relative thereto.

7. ln combination, a transverse bolster a truck iframe having an arcuate portion, brackets extending irom the ends ot said 'frame and attached to axles and wheels, springs means mounted on the ends of said bolster in the space between the ends of said arcuate portion of the truck trame, supporting blocks mounted on the ends oli' said arcuate portion, links depending therefrom having their tree ends connected to said spring means, said links being arranged to turn laterally with said blocks and to rotate i'reely tore and att in said blocks, and means to support said blocks on the ends et the arcuate portion ot the frame to permit said rotation relative thereto, and bearing sleeves on said supporting means between said supporting means and said blocks.

8. n combination, a transverse bolster, a trame having an arcuate portion and outwardly projecting ends, brackets projecting .trom said ends, axles and wheels connected thereto, said wheels being located within said brackets, a full elliptic spring mounted on the end ot said bolster on the outside ot said arcuate portion ot the frame between the Vends thereof, a semi-elliptic spring connected to the bottom halt oi' the full elliptic spring, links connected to the free ends of the semielliptic spring and supported on the free ends oi: the arcuate portion of the truck frame.

9. In combination, a transverse bolster, a frame having an arcuate portion and outwardly projecting ends, brackets projecting from said ends, axles and wheels connected thereto, said wheels being located within said brackets, a full elliptic spring mounted on the end oit said bolster on the outside of said arcuate trame between the ends thereof, a semi-elliptic spring connected to the bottom half o the full elliptic spring, links connected to the freev ends of the semi-elliptic spring and supported on the tree ends ot the k.arcuate port-ion of the truck trame, blocks pivotally mounted on the ends of the truck frame for supporting said links adapted to permit forward movement of said links thereon fore andaft thereof and to turn with said links when the links move laterally. Y

10. ln combinatioinav transverse bolster, a frame having an arcuate portion and outwardly projecting ends, brackets projecting from saidends, axles and wheels connected thereto, said wheels being' located wit-hin said brackets, a full elliptic spring mounted on the end of said bolster on the outside of said arcuate frame between the ends thereof, aV semi-elliptic spring connected to the bottom half ofthe full elliptic spring, links connected to the free ends of the semielliptic spring and supported on the free ends of the arcuate portion ofthe truck frame, blocks pivotally mounted on the ends of the truck frame for supporting said links adapted to permit forward movement of said links thereon fore and aft thereof and to turn with said links when the links move laterally, and means on the bottom of said links to engage yieldingly with the free ends of said semi-ellipticspring. e

ll. In combination, a transverse bolster, a unit on either end thereof consisting of a truck frame in arcuate form` having out-l wardly extending ends located over said bolster, a full elliptic spring having its upper half mounted on said bolster and the lower half therebeneath, said spring being located between ,the ends of they arcuate frame, a sen1i-elliptic relatively flat spring connected to the lower half ofthe full elliptic spring, links connected to said flat semi-elliptic spring at the bottomy thereof, said links being connected at their top te blocks pivotally mounted on the free end of said truck frame, said blocks adaptedk to turn with said links, bolts to support said blocks, bearing sleeves on vsaid bolts between said blocks and said bolts, brackets extending parallel to said springs from either ends of said arcuate frame, wheels and axles connected. to said brackets.

12. In combination, a transverse bolster,

an arcuate truck frame having its upper portion above said bolster and a lower porupper half of said full elliptic spring between the halves thereof, and brackets extending lfrom the free ends of said arcuate truck frame, axles and wheels connected to said brackets. l

13. In combination, in a spring support, of a spring, a rectangular link havingone end yadapted to support said spring on its transverse portion, the upper end resting on a rectangular block in a groove therein lso arranged that the link can move fore and aft of said block but Vwill turn laterally of said block, `a supporting bolt Vfor said block `and a bearing sleeve interposed between said block and said bolt.

In testimony whereof, I atlixl my signature.

THOMAS ELLIOTT.
